Hallmarks are the ID card of solid silver: they guarantee the purity and make it possible to tell real silver jewelry from plated pieces. Knowing how to read them is essential before buying or selling. Here’s a short guide to French silver hallmarks.
What a hallmark is for
In France, silver items intended for sale must be guaranteed by hallmarks that certify their purity (the proportion of fine silver). These tiny marks are stamped onto the piece of jewelry or flatware. A plated item never bears an official state purity hallmark — at best a “silver-plated” (métal argenté) mention or a maker’s mark. This is a key criterion for telling solid from plated silver.
The main French silver hallmarks
- Minerve head (French 925/950 hallmark): the guarantee mark for 925 and 950 silver on French items. A number (1 or 2) inside the mark specifies the purity. It’s the most common one on solid silver jewelry.
- Crab hallmark (800): marks 800 silver, often on export pieces or older items.
- Maker’s / manufacturer’s marks: a lozenge containing initials and a symbol that identifies the silversmith.
- Recense / import marks: for antique or imported items.
On antique silverware, you may also come across historical hallmarks (the “old man” head, etc.) depending on the era.
925 vs 800 silver: what the hallmark changes
The hallmark indicates the purity, and therefore the amount of fine silver — and thus the buyback value:
- 925: 92.5% fine silver (jewelry standard);
- 800: 80% fine silver (silverware, antique pieces).
At equal weight, a 925 item contains more fine silver than an 800 one, and is therefore worth more at buyback. The calculation is detailed in buying back silver jewelry.
Where to find the hallmarks
They’re discreet: look near the clasp of a chain, on the inside of a ring, under the handle or on the back of a piece of flatware, or under the base of an object. A magnifying glass is often needed. Compare them with reference hallmarks to identify the purity.
Blurry or missing hallmarks: what to do
A hallmark worn away by use doesn’t necessarily mean a fake, but it does call for additional verification: a touchstone test, an instrument test, and weighing. This is the job of a buyback professional, who confirms the purity in moments. This relates to the methods for spotting a fake silver bar in investing.
In summary
- Hallmarks guarantee the purity of solid silver; plated silver has none.
- Minerve head = 925/950; crab = 800; lozenge = maker’s mark.
- Purity determines the buyback value (925 > 800 at equal weight).
- Look for them at the clasp, inside rings, and on the back of flatware (with a magnifying glass).
